# Patch forward-ported from a gcc-3.0.x patch that adds -march=r10000 and
# -mtune=r10000 support to gcc (Allows the compiler to generate code to
# take advantage of R10k's second ALU, perform shifts, etc..

# Needs re-porting to DFA in gcc-4.0 - Any Volunteers? :)

# This is a very special patch -- it allows us to build semi-usable kernels
# on SGI IP28 (Indigo2 Impact R10000) systems. The patch is henceforth
# regarded as a kludge by upstream, and thus, it will never get accepted upstream,
# but for our purposes of building a kernel, it works.
# Unless you're building an IP28 kernel, you really don't need care about what
# this patch does, because if you are, you are probably already aware of what
# it does.
# All that said, the abilities of this patch are disabled by default and need
# to be enabled by passing -mip28-cache-barrier. Only used to build kernels,
# There is the possibility it may be used for very specific userland apps too.
